yes sir , absolutely i have done the same ...
x1 = (randi([0 3],1,N)); % RANDOM SIGNAL
x2 = randi([0 3],1,N);
%QAM modulation and alamouti matrix formation
y1 = qammod(x1,M);
y2 = qammod(x2,M);
y2c=-conj(y2);
y1c=conj(y1);
% ofdm - ifft -for N=64; EACH STREAM HAVING 64 , SUBCARRIER POINTS...
thank you sir, but in that paper the algorithm explained in such a way that , first we need to create the alamouti matrix(2x2), the 4 stream from two adjacent symbols. ofdm is suggested to do in the next step.
the paper is " Robust MIMO-OFDM System for Frequency-Selective Mobile Wireless...
hai all,
I am doing a project on OFDM - STBC , in which am using alamouti encoder in the first stage,i applied alamouti to the two datas a1 and a2 are consecutive data streams , i have created elements in alamouti encoder output matrix , that is a 4 data streams (a1 , a2 , conj(a1) ...
